RESUMO

OBJECTIVE: To compare the effects of three different rhinoplasty techniques on the postoperative cross-sectional areas (CSAs) of the nares and nasal vestibuli. STUDY DESIGN: Experimental study. SAMPLE POPULATION: Ninety-nine 3D-printed, remolded silicone models of a single French bulldog's rostral nose. METHODS: Models were fabricated based on a computed tomographic (CT) scan of the nose of a French bulldog with moderately stenotic nares. Each model underwent either vertical wedge resection (VW), modified horizontal wedge resection (MHW), or ala-vestibuloplasty (AVP) performed by a single surgeon (n = 33 per group). Preoperative and postoperative CT scans of the models were performed, and CSAs of the airway from the nares to the caudal end of the nasal vestibules were calculated. RESULTS: All three rhinoplasty techniques increased CSAs (adjusted p values <.001) but to different levels caudally within the nasal vestibule. Vertical wedge resection achieved this up to the start of the alar fold, MHW up to halfway between the nares and the alar fold and AVP up to the caudal nasal vestibule. Average percentage increases in CSA were 26%, 15% and 74%, respectively. Ala-vestibuloplasty led to larger CSAs than VW and MHW from the nares to the caudal nasal vestibule (adjusted p values <.05). The proportional difference within each technique was <7%. CONCLUSION: Ala-vestibuloplasty resulted in a larger increase in the airway CSA of silicone modeled nares and nasal vestibules of a single French bulldog in comparison with VW and MHW. CLINICAL SIGNIFICANCE: Ala-vestibuloplasty can be considered for French bulldogs with moderately stenotic nares and evidence of nasal vestibular stenosis.

RESUMO

OBJECTIVE: To describe the technique, outcome, and owner satisfaction associated with dorsal offset rhinoplasty (DOR) to treat stenotic nares in brachycephalic dogs. STUDY DESIGN: Retrospective case series. ANIMALS: Thirty-four client-owned dogs. METHODS: Medical records of dogs treated with DOR at a veterinary teaching hospital over a 6-year period were identified. Dorsal offset rhinoplasty was defined as removal of a dorsal wedge of nasal planum from each naris with apposition of the rostral abaxial tissue to the caudal axial tissue, resulting in translocation of the alar cartilage in both median and dorsal planes. Immediate and postoperative complications were recorded. Owners were asked to report any complications with healing of the nares and to score their satisfaction with the appearance of the nares. RESULTS: Thirty-four dogs met the inclusion criteria. Twenty-nine (85%) dogs were examined a median of 402.5 days (range, 23-2042) postoperatively, with no major complications related to the rhinoplasty recorded. Eighteen owners responded a median of 701 days (range, 37-1622) postoperatively. One owner reported that self-trauma led to collapse of one naris. One owner reported collapse of both nares within 4 years; timing and cause were unknown. Sixteen of 17 responding owners reported that they were very satisfied with the outcome of the rhinoplasty. The owner of the dog with the collapsed naris was very unsatisfied. One owner did not provide a satisfaction score. CONCLUSION: Owners were generally highly satisfied with DOR, and complications were uncommon. CLINICAL SIGNIFICANCE: This report describes an alternate technique to treat stenotic nares.

RESUMO

Brachycephalic obstructive airway syndrome is a common problem in certain breeds, and may necessitate surgical procedures, such as rhinoplasty, palatoplasty, laryngeal sacculectomy, and/or arytenoid laryngoplasty, to improve the quality of life. However, laryngeal edema may necessitate the use of temporary tracheostomy tubes postoperatively to maintain a patent airway. This case demonstrates that administration of nebulized adrenaline in the immediate postoperative period where upper airway obstruction is life threatening can be used to reduce edema, therefore avoiding the need for tracheostomy.

RESUMO

OBJECTIVE: To compare clinical features of brachycephalic airway syndrome and long-term surgical outcomes between pugs and French bulldogs and evaluate the influence of laryngeal collapse. METHODS: This retrospective study included 72 dogs that underwent wedge rhinoplasty and folded flap palatoplasty for brachycephalic airway syndrome. Epidemiological data, clinical signs, postoperative complications and owners' responses to a questionnaire at least six months after surgery were compared between pugs and French bulldogs. Spearman's rank correlation tests were used for associating laryngeal collapse with age and respiratory signs before and after surgery. RESULTS: On the basis of the results of the owners' questionnaires (available in 52/72 dogs), French bulldogs presented with lower activity levels and more severe digestive signs than pugs. Owners perceived clinical improvement in 88 · 5% of all dogs. The grades of respiratory and digestive signs were not different between the breeds in the long-term follow-up, and the grade of laryngeal collapse did not influence the grade of respiratory signs or surgical outcome. CLINICAL SIGNIFICANCE: Surgical treatment resulted in improved clinical signs in pugs and French bulldogs with brachycephalic airway syndrome, with a high owner satisfaction rate. There were no correlations between the severity of laryngeal collapse and overall respiratory signs or prognosis.

RESUMO

OBJECTIVE: To report reconstruction of a defect of the nasal plane and the rostral dorsum of the nose in a dog using a nasal rotation flap with Burow's triangles. STUDY DESIGN: Clinical report. ANIMALS: Mixed-breed dog (1.5 years, 8.6 kg). METHODS: A nasal defect caused by chronic granulomatous inflammation and involving the lateral nasal plane and adjacent rostral nasal dorsum in a dog was reconstructed and closed using a unilateral nasal rotation flap incorporating dorsal nasal plane tissue, with excision of Burow's triangles. RESULTS: The modified unilateral nasal rotation flap was effective in closing a defect of the rostral nasal dorsum. Incorporation of dorsal nasal plane tissue in the flap allowed for a cosmetic reconstruction of the lateral nasal plane defect (wing of nostril). CONCLUSIONS: Skin defects on the rostral dorsum of the nose and defects of the nasal plane in dogs can be closed and/or reconstructed using nasal rotation flaps incorporating nasal plane tissue.

RESUMO

This series describes five dogs with nasal polyps diagnosed between 2000 and 2011. Clinical signs included reverse sneezing, nasal discharge, epistaxsis, and stertor when breathing. Computerised tomographic findings included soft tissue mass, turbinate destruction, extension through the bony nasal septum and partial lysis of bones surrounding the nasal cavity. Three dogs were treated by dorsal rhinotomy, one dog was treated by ventral rhinotomy, and in one dog the polyp tissue was removed during nasal flushing. Three dogs have no clinical signs of nasal disease. One dog had confirmed recurrence of nasal polyps and was successfully treated with megavoltage radiation. One dog had recurrent nasal disease eight months after dorsal rhinotomy. Nasal polyps are a possible cause of nasal disease in dogs with nasal discharge, epistaxsis and stertor, and a differential diagnosis for dogs with extensive soft tissue lesions of the nasal cavities on computerised tomography. Nasal polyps can be treated successfully by rhinotomy in some cases but may reoccur.

RESUMO

O uso de costela autógena para correção de defeito criado no osso nasal em cães foi utilizado em 15 animais, separados em três grupos de pós-operatório, em que, após 30, 60 e 90 dias, finalizavam-se seus acompanhamentos. Cada grupo era composto de quatro animais enxertados e um animal-controle, no qual se utilizava o material do próprio defeito criado para coaptação. Os animais receberam monitoração clínica diária, e a integração do enxerto foi avaliada com exames radiográficos obtidos a cada 15 dias, quando se realizou o exame histológico. A técnica cirúrgica foi de fácil execução e possui praticidade em seu uso e foi suficiente para a correção de todos os defeitos criados. O efeito estético foi satisfatório, os exames radiográficos comprovaram a integração do enxerto, e a avaliação histológica evidenciou a presença de células compatíveis com a viabilização da técnica proposta.


The use of autologous rib to correct an experimental nasal bone lesion in dogs was performed in 15 animals, distributed in three post-operatory groups, and after 30, 60, and 90 days their clinical monitoring were finished. Each group was composed of four grafted animals and a control, in which it was used the material collected from the defect for coaptation. The animals received daily clinical monitoring and the graft integration was evaluated with radiographic exams taken every 15 days when the histological exam was performed. The surgical technique was easy to perform and had practical use. It was sufficient to correct all created lesions. The aesthetical effect was satisfactory; the radiographic exams proved the graft integration and the histological evaluation showed the presence of cells compatible with the viability of the technique.

RESUMO

OBJECTIVES: After a first clinical study showing a high prevalence of gastrointestinal tract diseases in brachycephalic dogs presented for upper respiratory syndrome, a prospective study was performed to determine the influence of medical treatment for gastrointestinal tract disorders associated with upper respiratory syndrome surgery. METHODS: The gastrointestinal tract and respiratory disorders of 61 brachycephalic dogs presented for upper respiratory syndrome were evaluated. Together with surgery of the upper respiratory tract, a specific gastrointestinal medical treatment was administered. A minimal follow-up of six months was required for inclusion. RESULTS: Palatoplasty with rhinoplasty was the most common surgical correction (88.5 per cent). The mortality rate in the perioperative period was 3.3 per cent. Minor complications accounted for 26.2 per cent of cases. No aspiration pneumonia was encountered. A sufficient follow-up was obtained in 51 dogs. The improvement was judged by the owners as excellent or good in 88.3 per cent of the respiratory disorders and in 91.4 per cent of the gastrointestinal disorders. Clinically, a statistically significant improvement was obtained for both respiratory and gastrointestinal disorders. CLINICAL SIGNIFICANCE: In comparison with other studies, digestive tract medical treatment combined with upper respiratory surgery seems to decrease the complication rate and improve the prognosis of dogs presented for upper respiratory syndrome.

RESUMO

OBJECTIVE: To describe and evaluate a technique involving a dorsal approach for the removal of the nasal septum in adult horses. STUDY DESIGN: Retrospective clinical study. ANIMALS: Four client-owned horses. METHODS: Access for partial nasal septum resection was through a dorsal nasal bone flap. Septum resection was performed because of reduced airflow from septal deviation and/or thickening caused by traumatic insult or neoplasia. Preoperative clinical signs and diagnostic results were recorded. Intra- and postoperative complications were noted and follow-up information was obtained from telephone interviews of owners or by clinical examination. RESULTS: The abnormal segment of the nasal septum was completely removed in all horses. A dorsal nasal bone flap approach provided excellent access to the septum and allowed immediate control of hemorrhage; blood transfusion was not needed. Cosmetic results were considered good to excellent by owners and horses returned to their previous level of work without perceived limitations associated with airway function. CONCLUSIONS: Nasal septum resection by the dorsal approach permits good observation of the abnormal septum, and provides exposure that facilitates removal of nasal masses and reduction of depression fractures with minimal complications. CLINICAL RELEVANCE: A dorsal nasal bone flap approach should be considered for horses that require nasal septum resection because it can be achieved with minimal hemorrhage, good cosmetic results, and return to function.

RESUMO

OBJECTIVE: To describe a surgical technique for, and report outcome after, extensive nasal septum resection in horses with congenital or acquired septal diseases. STUDY DESIGN: Retrospective study. ANIMALS: Horses (5) with nasal septal deformity. METHODS: Under general anesthesia, obstetrical wires were preplaced around the ventral, caudal, and dorsal aspects of the nasal septum by combinations of manual guidance (ventral and caudal wires) and use of a trephine hole on the dorsal mid-line (dorsal and caudal wires). The rostral part of the septum was incised with a scalpel and the ventral, dorsal, and caudal septal incisions were made with the preplaced wires. After septum removal, the nasal cavity packed with a tampon and a temporary tracheotomy was performed. RESULTS: The diseased nasal septum was completely removed in all horses. It was possible to direct the caudal cut at a sufficient angle so that the remaining stump was in a wide part of the nasal passage, where it would have minimal effect on airflow. Four horses healed, and returned to intended use but continued to make a slight respiratory noise during exercise. At 13 months after surgery, 1 horse with a concurrent wry nose was retired from race training after 2 additional surgeries failed to relieve exercise intolerance at high speed. CONCLUSIONS: The 3 wire-cut method of nasal septum resection was technically easy to perform and safe, allowed return to function in most horses, and produced an excellent cosmetic appearance. CLINICAL RELEVANCE: This technique for nasal septum resection allows removal of a large portion of the nasal septum and provides a safe alternative to conventional techniques of nasal septum resection in the horse.

RESUMO

Alapexy involves the creation and apposition of two small elliptical incisions, which fix the alae in an abducted position. Permanent alapexy was achieved in four of five dogs (eight of nine nostrils) that were operated. Four animals had significant improvement in their respiratory efforts because of reduced nasal obstruction. Although the alapexy procedure was somewhat more difficult to perform than simple wedge resection techniques, it may be a viable option in those animals where other techniques have failed or in animals that have dystrophic or flaccid alar cartilage. The alapexy technique may also improve the diameter of the nares compared to previously described techniques.

RESUMO

OBJECTIVE: To describe the clinical and morphologic characteristics of nasal dermoid sinus cysts in the dog. STUDY DESIGN: Retrospective clinical study. ANIMALS: Six client-owned dogs. METHODS: Medical records (1995 to 1999) of 6 dogs that had a discharging sinus in the midline of the nose removed surgically were reviewed for signalment, physical examination, surgical and histopathologic findings, and outcome. RESULTS: Three golden retrievers, 1 springer spaniel, 1 cocker spaniel, and 1 Brittany spaniel with a history of intermittent discharge from a small opening in the midline on the bridge of the nose at the junction between the nasal planum and the skin were identified. The condition was unresponsive to antibiotic therapy, and previous surgical excision had been unsuccessful in 3 dogs. None of the dogs had any other congenital defects, and all dogs responded to complete surgical excision of the tract and cyst. On histopathologic examination of excised tissue, there were adnexal structures along a tract lined with stratified squamous epithelium, consistent with a developmental abnormality of ectodermal tissue. CONCLUSIONS: The lesions were diagnosed as nasal dermoid sinus cysts, similar to the congenital condition described in humans. Nasal dermoid sinus cysts are rare developmental defects related to abnormal development of the pre-nasal space and may extend into the cranial vault causing cerebral abscesses or recurrent meningitis. Complete surgical excision has a good prognosis. CLINICAL RELEVANCE: This is a new condition that should be added to the surgical differential diagnosis for a discharging sinus over the external nares in dogs.

RESUMO

OBJECTIVE: This article reports an alternative to septal resection in nasal septal deviations involving the rostral 7 to 10 cm of the nasal septum. STUDY DESIGN: Case report. SAMPLE POPULATION: One client-owned foal. METHODS: A nasal approach with mucosal elevation was used to gain access to the cartilaginous portion of the nasal septum. Once exposed, a series of parasagittal incisions in the cartilage allowed the septum to be repositioned while providing some intrinsic stabilization. RESULTS: The nasal approach provided good access to the rostral 7 cm of the nasal septum. The technique resulted in minimal hemorrhage from the site. Bleeding was reduced with the use of ephedrine to vasoconstrict the mucosal vessels, and primary closure of the mucosa. CONCLUSIONS: Use of an intrinsically stabilized septoplasty should be considered as a means of decreasing the airway obstruction caused by nasal septal deviation in foals while allowing for normal development of facial contour.
